The BOA's medical adviser has seen the records of Idowu's recent private treatment for a nerve problem in his leg and back and is satisfied no fitness test is required.

But nobody has spoken to the 33-year-old - not even his coach Aston Moore, an employee of UK Athletics.

Perplexed: Van Commenee is unsure on the whereabouts of Idowu

Van Commenee said: 'We shall support him when we see him as we always have for 12 years. I am perplexed that in the last two weeks before the Games he chose to turn his back on us. I find it bizarre, Aston finds it bizarre.'

Idowu's competition starts on Tuesday but he must register at the Athletes' Village at least 48 hours earlier. 'There will be a room ready for him,' said Van Commenee.
